Beat the butter, sugar and egg with the whisk of the hand mixer for at least 10 minutes until frothy. Stir in spices, lemon peel and ground almonds. Mix flour and baking powder and knead with the dough hooks of the hand mixer. Form the dough into a ball with your hands, wrap in foil and chill for approx. 4 hours. Roll out the dough on a floured work surface to a thickness of approx. 5 mm.
Cut out dough with different motifs and place it on 3 baking trays lined with baking paper. Cover with flaked almonds and press lightly. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/gas: level 3) for 15-20 minutes. Remove and let cool on a cake rack
